The sequence below shows the number of bacteria Arjun observed each hour for a science experiment: 5, 20, 80, 320,1,280,... Which recursive function describes the number of bacteria observed at the nth hour? f(1) = 5 f(n+1) = 2f(n) + 10, f(1) = 1 f(n+1) = 5f(n), f(1) =1 f(n+1) = 4f(n), or f(1) = 5 f(n + 1) = 4f(n)
